The Convection And Moisture EXperiment (CAMEX) is a series of field
research investigations sponsored by the Earth Science Enterprise of
the National Aeronautics and Space Administration (NASA). The fourth
field campaign in the CAMEX series (CAMEX-4) ran from 16 August to 25
September, 2001 and was based out of Jacksonville Naval Air Station, ... Florida. CAMEX-4 focused on the study of tropical cyclone (hurricane)
development, tracking, intensification, and landfalling impacts using
NASA-funded aircraft and surface remote sensing instrumentation.
The Microwave Temperature Profiler (MTP) is a passive microwave
radiometer which measures the thermal emmission from oxygen molecules
in the atmosphere for a selection of elevation angles. Current
observing frequencies are 56.6 and 58.8 GHz. Measured brightness
temperatues versus elevation angle is converted to air temperature
versus altitude using a statistical retrieval procedure. An altitude
temperature profile is produced every three km along the flight path.
